Since you didn't quote me I didn't see your question except by chance.:D
Yes, exactly like that.
I can't read the details but the ones I got are adjustable from 35-75 lbs.
That basically relates to 35-75 mph.
One for OD and one for lockup.
I set them both as high as they would go and then started test driving and lowering the OD switch until OD was coming on where I wanted it, and then did the same with the lockup.
I hardly ever use lockup because of the rear gears I have but I will be changing to 3:55's before too long and I'm sure I will use it more.
Lockup and OD both allow the trans to run cooler because of a lack of friction.
I can even notice it on the engine temp when in OD and lockup.
